Title: Saddle-ride type four-wheel vehicle
Inventor: HANAFUSA SEIJI
IPC: B62K5/01
Filed: 2008-03-10
Abstract: To achieve mass concentration and to keep the center of mass at a low position when a water-cooled engine is mounted. In a saddle-ride type four-wheel vehicle, a radiator and a fuel tank are supported on lower frames, and arranged, side by side, so as to be distributed respectively on the right-hand side and on the left-hand side so as to overlap each other when viewed from a side. In addition, the fuel tank and the radiator are disposed at the rear of a front suspension arm and at the rear of an engine. As a result, the concentration of mass and the keeping of the mass at lower position are achieved. Moreover, the fuel tank and the radiator are allowed to stretch outwards beyond the upper frames. Consequently, the fuel tank can have a larger capacity and a ventilation path that leads to the radiator can be secured.

Inventor: SOEGER NICOLA
IPC: B01D53/94
Filed: 2007-05-04
Abstract: The invention relates to exhaust purification units for reducing the nitrogen oxides in lean-running exhaust gas from internal combustion engines by selective catalytic reduction using ammonia, wherein an excess administration of ammonia leads to undesired emission of unused ammonia. Said emissions can be reduced with ammonia trap catalysts. In the ideal case, ammonia is oxidised to nitrogen and water by said catalysts. This requires additional construction space in the exhaust system, which has to be taken from the volume provided for the SCR main catalyst where necessary. Furthermore, on application of such ammonia trap catalysts, over-oxidation of the ammonia to give nitrogen oxides can occur. According to the invention, the above problems can be overcome by means of a catalyst for removal of nitrogenous pollutants from diesel exhaust containing two superimposed layers. The lower layer has an oxidation catalyst and the upper layer can store at least 20 millilitres of ammonia per gramme of catalyst material. Said catalyst displays reduced ammonia leakage with good SCR conversions in the low temperature range and can be used as SCR catalyst with reduced ammonia leakage or as ammonia trap catalyst.
